"People like the fact they can bend it. You can use the toy on its own but the real fun happens when you can change it to the way you want to," he said.

MysteryVibe began planning the idea in 2008 and conducted a lot of research before it started on development.

According to the founders, the response to Crescendo has so far been very positive

"One thing we found is that women don't like penis-shaped toys. And also, around half of female sex toys are bought by men for their partners. Men are fine with buying a vibrator, but they feel maybe feel threatened by the idea of one that looks like a penis," Soumyadip said.

The company is seeking €50,000 (around £35,000) on crowdfunding site Born.com and, if successful, should ship the finished product in November 2015. Ensuring that Christmas can come more than once this year.

“What we saw in MysteryVibe was a real passion for challenging sexual taboos and supporting a true sex-positive environment. That’s why we decided to give them our full backing,” said Jean-Christophe Chopin, the founder of Born.

The Crescendo is manufactured right here in Blighty and Soumyadip says that, if successful, the company already has ideas for its next version that could launch next year.
